Segregation-induced ordered superstructures at general grain boundaries in a Ni-Bi alloy
Randomly selected, high-angle, general grain boundaries in a nickel-bismuth (Ni-Bi) polycrystalline alloy can undergo interfacial reconstruction to form ordered superstructures, a discovery that enriches the theories and fundamental understandings of both grain boundary segregation and liquid metal embrittlement in physical metallurgy. …read more
